Phases 1 and 2 were defined before 3G networks existed, and as such support adding IN services to a GSM network, although they are equally applicable to 2.5G and 3G networks. Phase 3 was defined for 3GPP Releases 99 and 4, and hence is a GSM and UMTS common specification, while Phase 4 was defined as part of 3GPP Release 5.
These components form a basic tariff system but, as telecommunication advances, tariff structures become increasingly more complex. [3] Usually there is the option of calling collect (in the UK known as reversing charges ), where responsibility for charges normally paid by the caller is accepted by the recipient.
OC-3 is a network line with transmission data rate of up to 155.52 Mbit/s (payload: 148.608 Mbit/s; overhead: 6.912 Mbit/s, including path overhead) using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and STM-1 ( SDH ).
